Normally this is wear in the 3-4 slider, and the 3rd gear drive gear. In 3rd there is a drive gear, and a driven 3rd gear, and the 3rd drive gear engages with the 3- 4 slider and should pop into place where it stays and gives you 3rd until you shift. Upon rare occasion the detents that help hold the 3- 4 slider into place will be bad and the gears will be good, but it is almost always the 3rd drive gear and the 3-4 slider causing the problem. BotXXXXX XXXXXne is the transmission has to come out and apart to fix this type of problem. Also this type of problem normally circulates steel fragments from the damage, and this is real bad on the other gears. If you catch it early enough the damage is normally isolated to the parts discussed. If you have any more questions I am here to help.

Hello, Sorry it has taken me so long to respond. Can you send me a blow-up picture of the gear case and point out exactly what parts you are talking about. You are using terminology that I cant find in the references I am using. Thankyou
I don't have a blow up, sorry about the terminology gap. The slider is the piece the shift fork engages into. The slider gets pushed towards the synchro when you shift, captures the synchro, and then the gear (drive gear) to complete the shift into the gear you choose. The driven gear it the gear the drive gear is meshes with and turns or drives. The drive and driven gears are always in contact with each other, but they are not locked in to the power from the engine until the slider captures one of the drive gears to put the trans into gear, all the other gears are in contact, but they freewheel, until you choose that gear and the slider locks into position to complete the shift. The detents are spring loaded pieces that prevent the slider form moving around on its own, and their job is to help the slider locked into position when you make a shift to keep the trans from jumping out of gear.
